Title
(EN) RESILIENTLY FLEXIBLE BRISTLE BEARING HEAD TOOTHBRUSH
(FR) BROSSE A DENTS A TETE SOUPLE, ELASTIQUE, POURVUE DE POILS
Abstract
(EN)
A toothbrush having a handle (2) and a resiliently flexible bristle-bearing head (1) wherein, when the toothbrush is in its normal stress-free configuration, the free ends of bristles lying along a longitudinal and/or transverse axis of the brush form a generally concave profile (9) adapted to suit the buccal surface of the teeth (10). The toothbrush head (1) can flexibly conform to a convex profile to suit the labial surface (12) of the teeth (10) or to avoid damage to the gums (18).
(FR)
L'invention concerne une brosse à dents se composant d'un manche (2) et d'une tête (1) souple et élastique supportant les poils, lorsque ladite brosse est dans sa position normale non sollicitée, les extrémités libres des poils reposant le long d'un axe longitudinal et/ou transversal de la brosse forment un profil généralement concave (9) conçu pour s'adapter à la surface buccale des dents (10). La tête (1) de la brosse à dents peut s'adapter de manière flexible à un profil convexe pour épouser les contours de la surface labiale (12) des dents ou pour éviter d'endommager les gencives (18).
